Newline Converter

换行符转换是一款免费的在线开发工具,无需下载安装、无需注册登录,打开网页即可使用。不同操作系统使用不同的换行符:Windows 用 CRLF(回车+换行)、Unix/Mac/Linux 用 LF、旧版 Mac 用 CR。本工具会先把文本统一归一,再转换为你选择的目标换行符,解决跨平台打开文件时出现的多余空行、显示错乱或 Git 提示换行差异等问题。所有处理均在浏览器本地完成,数据不上传服务器。

换行符转换适用于在 Windows 与 Linux/Mac 之间迁移代码与脚本、修复 Shell 脚本因 CRLF 无法执行、统一团队仓库换行风格、处理配置文件与数据文件等场景。作为一款轻量在线工具,它免去了在编辑器里逐一设置的麻烦,随开随用,是开发调试与运维处理中的实用小工具。

使用教程
  1. 粘贴文本到输入框,或选择一个 .txt 文件自动载入。
  2. 选择目标换行符(LF、CRLF 或 CR)。
  3. 点击「转换换行符」,浏览器本地完成归一与转换。
  4. 点击「下载结果」保存换行符已统一的文件。
常见问题
Q1:为什么结果看起来没变化?
A:换行符差异在文本框中不可见,转换效果在下载的文件里生效,可用支持显示换行符的编辑器查看。
Q2:CRLF 和 LF 有什么区别?
A:CRLF 是 Windows 换行,LF 是 Unix/Mac/Linux 换行,混用会导致空行或脚本报错。
Q3:数据会上传吗?
A:不会,全部在浏览器本地处理。
Q4:会破坏文件内容吗?
A:不会,仅统一换行符,正文内容完全保留。
Q5:Git 老提示换行符警告怎么办?
A:可用本工具把文件统一为 LF,或配置 Git 的 core.autocrlf;统一换行风格后警告即消失。
换行符转换可以在手机上使用吗?
A:可以,本工具基于网页运行,手机、平板、电脑均可直接打开网页使用,无需安装 App。
